Description

1-Cyclohexene-1,4-Dicarbonyl Chloride (7Ci,8Ci) is a highly reactive, bifunctional acid chloride derivative of cyclohexene, serving as a critical building block in advanced organic synthesis. Its dual acyl chloride groups make it an indispensable precursor for constructing complex molecular architectures, particularly in the development of specialty polymers and active pharmaceutical ingredients (APIs). This compound is essential for research and production chemists in the pharmaceutical, agrochemical, and advanced materials sectors seeking to introduce rigid, functionalized cyclohexene cores into their target molecules.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of novel drug candidates, particularly those requiring a rigid, bicyclic or polycyclic scaffold.
• Polymer Chemistry: Serves as a monomer or cross-linking agent for producing high-performance polymers, polyamides, and polyesters with enhanced thermal and mechanical properties.
• Agrochemical Synthesis: Used in the manufacture of advanced herbicides and fungicides, where the cyclohexene structure contributes to biological activity.
• Ligand and Catalyst Development: Foundation for creating sophisticated chelating ligands and organometallic catalysts used in asymmetric synthesis.
• Dye and Pigment Manufacturing: Intermediate in the production of specialized organic dyes and pigments for industrial applications.
• Material Science Research: Employed in R&D for developing new organic electronic materials and liquid crystals.

Quality Control

Our 1-Cyclohexene-1,4-Dicarbonyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the stringent requirements of advanced synthetic applications. Certificates of Analysis (COA) documenting identity, purity, and impurity profiles are available for every shipment upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature and reactivity as a strong acid/organic solvent, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and degradation. Keep away from heat, open flames, and incompatible materials such as bases, alcohols, and amines.
